The workflow validates the manifest against its declared schema and checks the manifest version against pushed release tags. ChangesMCP manifest validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR adds the registry manifest and tag validation, but the current head still permits a known-invalid artifact hash to proceed toward publication and can accept a tag while the artifact identifier remains stale; required audit-log configuration documentation is also missing. Merge should wait for these issues to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Correction to my earlier blocked verdict: that verdict is superseded. For exact unchanged head At #1893 head The proposed six-line guard was rejected and reverted because it runs on the tag before #1893 can create the artifact. With the intentionally committed placeholder, it would fail every release and instruct maintainers to commit a digest that does not exist yet. The registry does not receive the placeholder.

Independent adversarial review of exact head 8ac628d. Verdict: blocked by one confirmed validation-boundary issue.
Other evidence:
No other actionable findings across completeness, correctness, security, duplication, scope, or over-engineering. |

Fixed in d906c5b by pinning the official MCP Registry schema URL and performing typed exact equality in jq before any fetch. The regression now rejects attacker URLs, missing/null/non-string values, HTTP downgrade, wrong paths, and an official URL with a trailing newline before the curl sentinel can run. The checked-in manifest still validates against the official schema; actionlint and zizmor pass. |

- Around line 62-66: Extend the validation around server_version in the release
workflow to inspect every packages[].identifier entry in server.json and require
its embedded version to match the pushed tag, not just the top-level version.
Make the tag job fail with a clear error when any identifier is stale, while
preserving the existing server.json.version validation and guidance for updating
related MCPB metadata.

Independent adversarial gate for exact head
Conclusion: no actionable findings across completeness, correctness, security, bugs, duplication, reuse, or scope/over-engineering. |
Adds server.json at the repo root under the io.github.leanercloud namespace (permanent once published -- GitHub-OIDC-verified, casing matches the registry's io.github.<org> examples). The registry has no raw-Go-binary package type, so the single packages[] entry is registryType "mcpb", pointing at the (not-yet-existing) GitHub Release MCPB asset the follow-up release.yml PR will produce; fileSha256 is a placeholder 64-zero hash until that PR wires up patching it from the actual built artifact at publish time. environmentVariables documents both CUDLY_MCP_ENABLE_REAL_PURCHASES and CUDLY_MCP_AUDIT_LOG openly, per the registry's financial-transactions disclosure requirement. .github/workflows/mcp-server-json.yml validates server.json against the registry's published JSON Schema on every PR that touches it, and on v* tag pushes asserts server.json's version matches the tag -- a mismatch fails the workflow loudly rather than letting a later publish step silently ship the wrong metadata (the registry rejects republishing a version anyway, so this catches the mistake before that point).
Prevent pull request content from selecting the schema used to validate server.json. Require the manifest declaration to exactly match the pinned official Registry schema before fetching it.

In @.github/workflows/mcp-server-json.yml:
- Around line 75-76: Update the release guidance message in the workflow to
instruct maintainers to correct server.json.version and retag after a tag
failure, removing the direction to manually update packages[].identifier or
packages[].fileSha256.
- Line 47: Update the schema download curl invocation to include explicit
connection and total-transfer time limits via --connect-timeout and --max-time,
while preserving the existing URL, output path, and failure behavior.
In `@server.json`:
- Line 19: Update the server manifest’s environmentVariables list to document
the optional CUDLY_MCP_AUDIT_LOG setting alongside
CUDLY_MCP_ENABLE_REAL_PURCHASES, including its runtime semantics so MCP clients
can configure audit logging correctly.

Independent adversarial review evidence for exact head The first full-diff review found two valid defects:
Commit Three fresh independent reviewers then examined the complete five-file diff and reported no actionables or nitpicks. They covered Registry schema and namespace semantics, workflow permissions and triggers, dependency-lock integrity, URI validation, tag behavior, environment metadata, #1891/#1893 ownership boundaries, macOS/Linux support, and the absence of Windows work. Three consecutive exact-head verification passes each completed:
